A 0.51 kg rock is projected from the edge of
the top of a building with an initial velocity of
10.9 m/s at an angle 58◦
above the horizontal.
The building is 6.89 m in height.
At what horizontal distance, x, from the
base of the building will the rock strike the
ground? Assume the ground is level and
that the side of the building is vertical. The
acceleration of gravity is 9.8 m/s
